I still think this is flawed data. You cannot say with any degree of certainty that 4 hits are going to neutralize every enemy, so how can you give it a 100% probability of incapacitating an opponent? Sounds nice for a video game, but real life does not work that way. If that was the case I would carry the Beretta 84 (14 shot 380). This data does not take into account the effectiveness of the projectile being used, it lacks any credibility.
For what its worth, back in the revolver days, I was taught on multiple assailants to put one in each one, starting with the highest threat and return to those that need followup.
Tactics usually play a significant role in the outcome of a gunfight, cover, cover,cover.
My rifle and pistol are tools, I am the weapon.
